VAPOR-BURNER.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application led March 20, 1916. Serial No. 85,339.

,lene, kerosene, alcohol and other oils vor spirits are vaporized and. mixed with air,

said mixture being supplied to a mantle.

Among the objects of this invention is to provide a burner,` which is simple and inexpensive-in construction and eiicient and economical in operation.

Another object is to provide a burner, the parts of which can be easily disassembled for the purposes of cleaning and repairing when necessary and by which the constituent parts of the fuel mixture may be read' ily adjusted so as to produce a steady and maximum amount of light.

Further objects will be apparent from the following description.

To these ends my invention comprises the features of construction and combination of parts hereinafter more particularly vdescribed and claimed.

In the drawing formin part of this specification, Figure 1 isa si e elevation of my improved burner, parts of the structure being broken away and in section; Fig. 2 is a section taken on the line X-X of Fig. 1; Fig'f is a section on the line Y--Y of Fig. l, and Fi 4 is a perspective of the removable auxi iary generator forming part ofthe invention.

In the drawin A indicates the main vapor generator W ich is in the form of an upri ht tube having connected to its lower end, y the couplin 2, a valve B, which controls the supply o fuel from the pipe 3'to the main generator, said pipe leading to any source of fuel such as sure not illustrated. Y

Mounted upon the upper end of the main generator tube is a burner head C having a horizontal body portion 4 turned downwardly at each of its ends, one end 5 having an internal thread 6. Secured to the end 5 by an externally threaded collar 7 is a mantle holder 8 of usual construction upon which is secured in any well known manner a mantle 9 of usual form. The opposite end 10 of gasolene under presthe burner head terminates in a depending Bunsen tube 11, the passage through which extends upwardly and longitudinally through the burner head and downwardly into the mantle. The lower end of the Bunsen tube has formed in its side an air 'admission opening 12, the size of which may be regulated by turning a collar 13, having a threaded connection about the lower end of the Bunsen tube over said opening. The lower end of the tube 11 is closed by a transverse wall 14 arranged a shoft distance above its lower extremity, said wall being formed with a centrally disposed opening 15. Associated with said parts is am auxiliary vapor generator 16 in the formof along thin tube having on its upper end a connecting head 17 of cylindrical form having one end formed with a conical point 18 and a stem 2 extending downwardly from the needle lslides. A cap nut 28 threaded on the cylindrical member 22 comprises the packing member 26 and completes the formation of a gland through which the needle member is adapted to slide. A link 29 secured to the lower end of the stem 27 is adapted for sliding the cleaning needle back and forth. The point of the cleaning needle is adapted to enter the orice 24 when the needle is pushed upwardly to remove any foreign substances and clean said orifice from time to time as desired.

A side of the burner head is formed with two supportiuiop lugs 30 and 32 aced apart and between w ich the head 17 1sv admitted. The lug 30 is formed'with a passage 31, which is adapted to form a connection between the passages 20 in the head 17 and .the main vapor generator tube A. The up- 30, the shank of a' in the head 17 seated. When so seated, it wil be seen by reference to Fig. 1 that a tight passage is formed between the main and auxiliary generators The lower end of the auxiliary vaporizing tube 1.6 is formed with an elbow 35, so that'in use the main portion of the tube 16 depends from alongside of the burner head and its lower end extends through a slot 36 and into an opening or socket seat 37 in the lower extremity of the Bunsen tube with the nozzle 38 of the cylindrical body 22 entering the opening 15 in the wall 14, said auxiliary vapor generator being held or interlocked securely at its lower end in said position thereby. Both the main-and auxiliary generator tubes are arranged in close proximity to the mantle 9, so that the heat generated by the mantle will heat said tubes, and cause elicient vaporization of the fuel, and more thorough mixin of the fuel constituents in the Bunsen tu e. The main vapor generator contains a wick 40 of straining material made of asbestos or other suitable material, which collects any foreign substances in the li uid fuel, which is admitted by the valve B into the burner and retards its iow somewhat, so that an excessive amount of liquid fuel is prevented from entering the tube 16.

In operation heat is applied to the elbow 35 such as by holding a lighted match in proximity thereto. The fuel supply valve B is then gradually' opened, heat being applied to the elbow untll gas will i nite over the mantle 9. The regulating colar 13 is adjusted, so that the proper amount of air entering the opening 12 mixes with the gas or fuel which is admitted through the oriice 24 to produce a brilliant light by the mantle. Should the orifice 24 give any indication of clogging such as by uneven burnin of the gas, the cleaning needle 25 is pus ed up into the orifice and pulled down again quickly while the lamp is burning. This is repeated as often as is necessary until the mantle burns steadily. To avoid any gas escaping from leaking joints, the nut 28 and bolt 34 are tightened. When it is desired to clean the main generator, the nut 2 is loosened, and the tube A and wick 40 removed. The wick is then washed in gasolene or other suitable medium or replaced by a new wick and the parts re-assembled. To clean or replace the auxiliary generator, the bolt 34 is loosened and the generator tipped forwardly and down until the end 21 and cylindrical member 22 slip out of their sockets in the Bunsen tube.

In accordance with the patent statutes, I have described the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have' it understood that the construction shown is only illustrative, and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claims.
